.T all 'tU/LOTIt it may concern:

Be it known that we, H- RRY HiNKs-MAR- m,- ALEXANDER WILLIAM CA RON,and' PERCIVAL canes PA'QKMAN, subjects of the King of England, residingat andyvhose postoffice address is 23 Denmark Place, Charing CrossRoads, London, in the county of London, England, have invented certainnew and useful Improvements in Talking-Machines and we do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertainsto make and use the same. This invention relates toimprovements in sound conveyers for talking machines, and its object isto rovide an attachment for use with the U-tu e or goose neck of agramophone, whereby the position of. the sound ox, with relation to therecord may be changed so that the same sound box may be used, in themost effective playing position, with the hill and dale track of araphophone record as well as with the zig-zag track of a gramophonerecord.

In order that the best results may be produced with the zig-zag record,it is desirable that the sound box be disposed parallel to the tone armor tangential to the spiral track of the record, so that the needlemoving in the zig-zag course will properly 0 erate the diaphragm of thesound box. 0 also with a hill and dale record, out in a disk,- the bestresults are produced when the needle bar. and needle are disposedinradial relation to the pivotal axis of the tone arm, with the soundbox disposed laterally of the vertical plane cutting said needlesandtone arms pivotal axis and hence disposed laterally.of the spiralhilland dale track. It will be understood that, with the disk record of thistype, the distancefrom the pivotal axis of the tone arm to the needle issubstantially the same as the distance from said axis to the center ofthe rotating support carrying the disk record, so that the needle willswing sub-' stantially in an are passing through the center of therecord.

\Ve are aware that it is not broadly new to provide an adapter tube orconnection to enable the same sound box to be interchange ably usedwitha"hill and daleor a zig-' zagrecord. The present-invention is, therefore,not only designed to accomplish this end, but also to accomplish it insuch a manand dale record 1 Her that the sound box will be properlydisposed with relation to the record to produce thebest results.

To more fully describe the invention reference is had to theaccompanying drawings illustrating practical, embodiments of the same,in which drawings like letters designate the same parts in the severalviews, and in which V Figure 1 is a view in side elevation, showing theinvention associated with the goose neck of a gramophone, with the soundbox in the most efic'i-tive position for playing a disk record of thehill and dale type. Fig. 2 is a plan view of same. Fig. 3 is aperspective view of the improved attachment, and Fig. 4 is ,a similarview of a modified ,form of adapter.

a shows the ordinary U-piece or goose neck ords,'the goose neck a beingpivotally connected to the tone arm n to permit the goose neck a,toswing vertically.

The improved attachment or adapter consists of a tubular connectionrepresented in Figs. 1, 2 and 3 by the curved elon ated portion I)terminating at its u per end with the lateral extension c provi ed witha pin (1 operating in the bayonet slot of the goose neck, the end 0being adapted to be detachably connected with the open end of the gooseneck member. The other, or lower, end of the elongated portion 1) of theconnecting tube extends upwardly and is adapted to directly receive thesound box, the upwardly directed end 6 being providedwith a .bayonetslot f forming a locking means with the usual pin of the sound box. Itis obvious, however, that any other suitable attaching means may beemployed at either 01' both ends of the connecting tube. Similarly inthe modified form shown in Fig. 4 the arts curved portion 1), we providea straight tube the depending portion 6 having coin risin the ateralupper extenslon c and-the lower upwardly directed extension c.

It will be observed that when it is-desired to play a record of thefzig-zag type the improved attachment is omitted and the sound'box isdirectly connected with the openend of the oose neck, -butwhena -hill isto be played the attaclh ment is aflixed to the open end of the gooseneck by means of the extension 0, or c, and the sound box 'is directlymounted on the upwardly directed lower portion e, or e, with the soundbox in the most effective playing position relative to the record andwith the needle in proper alinelnent with the axis of the tone arm.-

Having thus described the invention'what we claim is A talking machinesound conveyer comprising a sound box, a tone arm, a goose neck swln mgon said tone arm and communicating t erewith, and a tubular connectionbetweenthe sound box and the goose neck,

.said connection consisting of a horizontal portion, fitting said gooseneck, thence extending downwardly, and thence extending upwardly andterminatin axially in alinement with the axis of said tone arm, with 20'HARRY HINKS-MAR'JIN'. ALEXANDER WILLIAM CAMERON. PEROIVAL JAMES PAOKMAN.
